DCat is 16, has a medicated thyroid condition. Two clean litter trays, 2 Feliway plug-ins plus daily Feliway spray in other rooms. He is still pooing up to 3 times a day outside the tray. He often gets muddled and doesn't go outside often or for long. He mostly seems to try to steal food (eats 5 pouches a day plus Wellbeloved senior biscuits). I am at the end of my tether. I can't bear to euthanise for such a trivial reason but nor can I bear the unsanitary state of the house. I use cleaning products which break down the wee and poo odours.
Any ideas? TIA
